Sumana is the best host. She is very helpful, attentive and friendly. You can get everything you need in the room, from microwave, utensil to first-aid kits.
If you are a fan of street food, here is the right place for you. However, you can find many local restaurants which Thai-basil pork with rice(Kao Pad Kra Prao) costs just 1€, heaven!
If I have chance to visit bkk again, Sumana's place will be my first choice.
